FreeBSD 3.4-STABLE with the routed changes of Feb 17.
>Description:
There have been various changes to routed on Feb 17. I am now
experiencing a strange message when routed is started:
routed: possible netmask problem between fxp0:192.168.1.4/32 and fxp0:192.168.1.0/24
routed: Send mcast sendto(fxp0, 224.0.0.9.520): No route to host
If have the following ifconfig lines on the machine in question:
ifconfig_fxp0="inet 192.168.1.3 media 100BaseTX mediaopt full-duplex"
ifconfig_fxp0_alias0="inet 192.168.1.4 netmask 0xFFFFFFFF"
As we can see, 192.168.1.4 is an alias for the machine.
ifconfig -a tells me:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.3 netmask 0xffffff00 broadcast 192.168.1.255
inet 192.168.1.4 netmask 0xffffffff broadcast 192.168.1.4
ether 00:a0:c9:ca:18:64
media: 100baseTX <full-duplex> status: active
supported media: autoselect 100baseTX <full-duplex> 100baseTX 10baseT/UTP <full-duplex> 10baseT/UTP
I have never had problems with this setup. OK, I still don't
have problems (everything is working) but the message is confusing.
I assume it would go away with a different netmask for the alias
but this would be wrong, I think.
>How-To-Repeat:
Configure a machine similar as above. Start routed.
